If you're not using a platform with cloud-init support (i.e., you're building a VM manually, not provisioning it through a cloud provider), you'll need to refer to [trick #1](https://spinningmatt.wordpress.com/2014/01/08/a-recipe-for-starting-cloud-images-with-virt-install/) and [trick #2](http://blog.oddbit.com/2015/03/10/booting-cloud-images-with-libvirt/) for a means to override the automated setup, apply a manual password to the CentOS account, and enable SSH password logins.
